Our industry creates values


Chemical water pre-treatment allows to treat the same amount of wastewater with:
18% less energy required
25% less tank volume needed
32% more biogas production


Inorganic coagulants are pivotal for safe drinking water and efficient wastewater purification. They
are produced in Europe, thus ensuring a reliable local supply.


Coagulants are essential for protecting human health and improving environmental performance. INCOPA members are committed to the highest product quality and environmental standards in Europe.


Chemical water treatment is the most cost efficient and state of the art technology. Coagulant use represents only 0.5% of the total cost of water purification (0.5€ on 100€, per person per year).


Our products contribute strongly to the Circular Economy.
Iron and aluminium coagulants’ raw materials are
mostly sourced from by-product streams, and therefore contribute to save virgin resources.
